Question

The graph of y = f(x) is shown below. What are all of the real solutions of f(x)
= 0?

Answer 1

x = -8, 0 and 6

Explanation:

Graphed function in the picture,

y = f(x)

Solutions of a function are defined by the points on x-axis where the graph intersects or touches.

In the given graph, curve of the function touches the x-axis at x = -8 and crosses the x-axis at x = 0, 6

Therefore, real solutions of the function 'f' will be x = -8, 0 and 6.
